HP130P torch height controller
HP130P torch height controller is equipped with constant current plasma source. When the distance gets farther，the arc voltage increases; On opposite, the arc voltage will decrease. Torch height controller will inspect the voltage change, then control the distance between cutting torch and material via the lift motor.
Generally, the instruction will list all the cutting parameters for some type of plasma. The user can refer to these parameters. Adjust the voltage in controller to match the selected current. The torch height will keep constant under regular speed.
